Product Technology
This chapter presents the general system technology and the available protection architectures for
Cisco’s dense wavelength division m ultiple xin g (D WDM) m etro sy st em, the Cisc o ONS 152 00.
1.1 Optical System Description
The ONS 15200 DWDM metro system transports da ta over wavel engths using fiber-optic cables. The
ONS 15200 operates in the 1550 nm transm ission win dow. Over a single optical fiber pai r, the ONS
15200 can carry up to sixtee n channe ls of data in the follo wing bit ra tes and for mats:
Protected or unpro tec ted da ta can tra nsmi t ov er the ON S 1 520 0.
The optical layer is independent of the electronic protocol that is external to the ONS 15200 system. You
can use any hig her-level p roto co l, inc lud in g pro pri et ary p rod uc ts, wit hin the ON S 1 5200 sy stem . Any
protocol used must fulfill the requirements listed in this book, including the bit rates listed in this
section.
1.2 Optical Channels
In the ONS 15200 system, optical channels transport informatio n between two client-layer interface
ports. All optical channels in the ONS 15200 system are duplex channels, which means that traffic flows
in both directions. The optical channels can be unprotected, as described in the “Unprotected Channels”
section on page 1-1 , or pro tected , as descr ibed in the “Pro tected Ch ann els” section on page 1-2.
1.2.1 Unprotected Channels
In an unprotected channel, protection fiber is not available. Only one fiber sends traffic to the client layer
of the receivin g no de . You can use unprotecte d chann el s wher e pro tec tio n is n ot ne ede d or if th e cli ent
layer provides pro t ect ion. Cisc o re co mm ends t h at you on ly u se pro tec ti on in o ne l ay er a nd avoi d

2.1 ONS 15200 Network Configurations
The ONS 15200 operates in several network configuration arrangements. All ONS 15200 configurations
consist of one or more ONS 15252 Mult ichannel Un its (MCU) or ONS 15201 Single -Channe l Units
(SCUs). The following inf ormation describe s some standar d ONS 15200 network configura tions,
including:
• The “Bus Confi guration ” sect ion on page 2-1
• The “Ring Conf igurati on” section on page 2-2
• The “Dual-Home Configuration” section o n pag e 2-3
• The “Multichannel Point-to-Point Configuration” section on page 2-3
CHAPTER
2
• The “Ring Configuration with Hubbed and Meshed Traffic” section on page 2-4
• The “Full-Mesh Configuration” section on page 2-5
2.1.1 Bus Configuration
In an ONS 15200 system bus configu ratio n, waveleng th channe ls link an ONS 152 52 MCU to ONS
15201 SCUs. Use this confi guratio n only in networks where opti cal-la yer fibe r protec tion is
unnecessary. It is possible to configure the bus configuration for layer-3 load-sharing protection or client
layer 1+1 APS, but the two data traffic flows would need to share the same optical fiber path, and
therefore protecti on would be incomple te.
In the bus configuration, the Client Layer Interface Port (CLIP) modules located in the ONS 15252 MCU
and in each ONS 15 201 SCU excha nge data. Figure 2 -1 illustrate s the ONS 15200 syste m bus
configuration.
NoteThe physical connec tion in Figure 2-1 consists of two fiber-optic cables.

2.1.3 Dual-Home Configuration
In the dual-home configuration, a pair of ONS 15201 SCUs share the total data traffic load between two
different fiber-optic cable (fib er) rou tes. The pai r of ONS 15201 SCUs can use id entic al or different
wavelength channel s to comm unicate with thei r respec tive ON S 15252 MC Us. Usin g ident ical
wavelength channels conserve s network resource s. In addit ion to load sha ring, the dual-hom e
configuration pro vide s tr affic pro tec tio n in the el ect ro nic cli e nt-la ye r dom ain . If one fi ber rou te is lost,
the data traffic shifts to the other fiber route in the client layer.
In addition to protecting traffic at the client layer, the dual-home configuration protects the ONS 15200
system against single MCU or SCU failures. Figure 2-3 illustrates the ONS 15200 dual-home
configuration.
NoteThe physical connec tion in Figure 2-3 consists of two fiber-optic cables.

2.1.4 Multichannel Point-to-Point Configuration
In the ONS 15200 multichannel, point-to-point configuration, multiple wavelength channels exist
between a pair of ONS 15252 MCUs. You can set up the multichan nel point- to-point configur ation wit h
or without optic al-l ay er pro tec ti on. Co nfi g uring op tica l-l ay er prot ect ion r eq uire s d ual fibe r ro utes.
In the ONS 15200 multichannel, point-to-point configurations, dual fiber routes send information along
two separate fiber routes . The dual physical rou te configu ration suppo rts SONET or SD H add/drop
multiplexer (ADM) prote ction and c lient-la yer 1+1 APS prot ection.
Cisco does not r ecom mend impl eme nti ng layer-3 l o ad-sha ring p rote ction i n a mu ltic ha nnel
point-to-point confi guration because the two netwo rk fiber rout es need to share an ONS 15252 MCU,
and any failure of the ONS 15252 MCU would cause both routes to disappear simultaneously . Figure 2-4
illustrates the ONS 15200 multichannel, point-to-point configurations.

3.1.2 ONS 15201 SCU
The ONS 15201 SCU communicates with the othe r nodes in the ONS 152 00 system on a spe cific
wavelength or channel. T he SCU use s a single CLIP mo dule . From th e DWD M lay er, several chan nels
of information, eac h occup ying a wav elength , enter t he ONS 15201 SCU. Each D WDM cha nnel of
information can enter the ONS 152 01 SCU from the A side, the B side, or the A side and B side .
The Collector Filter module (CFM) drops and transfers the specific channel or wavelength intended for
the ONS 15201 SCU to the CLIP module. For protected channels, the CFM drops the chann el from the
A side and B side. For unprotected channels, the CFM drops the channel from either the A side or B side.
The CLIP transfers information originating at the ONS 15201 to the CFM for protected channels. The
CFM splits the information and transmits it at a specific wavele ngth or channel in op posite direction s on
the A side and B side. The CFM does not split unprotected channels; it transmi ts the m directly to ei ther
the A side or B side. Information carried on a wave length or channel inte nded for ano ther ONS 15200
node passes through the ONS 15201 SCU without inte rferenc e except for the insert ion loss cause d by
the unit. Figure 3-3 shows a functional repr esenta tion of an ONS 15201 SCU.

the CLIP is further away from the NCB, you must install additional NCB modules.
Release 1.1 allows you to co nfigure up to two activ e NCBs as mana gers of any CLI P in a network . To
manage the CLIP, it must be no further than two CAN and two QPP hops away from the NCB. Any NCB
in a network that is not provisioned as an active manager of a CLIP can still inventory the CLIP.

Maintenance Manager
The CLI interf ace r esid es on the NCB mo dule and op er ate s o n th e data base serv er f or t he O NS 15200
system. The CLI interface has two modes of access for users—read-and-write access and read-only
access. Users are separated into three categories: administrator, operator, and guest. Each category has
different privileges:
• Administrator—read-and-write access to security management data
• Operator—read-and-write access to ne tw ork m an agem ent dat a
• Guest—read-only access to network ma nagement data
To access the CLI interface, use the Eth er net port on the NCB m odul e or the MA int erfa ce o n the C IM
module. MA interface access requires a EIA/TIA-232 cable.
4.5 Maintenance Manager
The Maintenance Manager (MM) interactive software tool, installed on a laptop or PC, provides a local
craft interface for the ONS 15200 system. The MM software provides access to the internal data bus at
ONS 15252 MCUs or ONS 15201 SCUs. It also facilitates access to data from isolated ONS 15201 SCUs
in the ONS 15200 network.

5.2 Client Layer Interface Port Module
The CLIP module provides the input port from the client layer to the integrated ONS 15200 system, and
the output port from the integrated ONS 1520 0 to the client la ye r. The CLIP module receives an optical
input signal from the client layer in either the 1310 nm or 1550 nm wavelength regions and converts the
78-13766-01
Cisco ONS 15200 Product Description

Communication Interface Module
optical signal to a specific International Telecommunication Union (ITU-T) G.692-compatible
wavelength. The C LIP mo dule then transf ers the converted optical s ignal to the DW DM side of the ON S
15200 network.
When the CLIP module receives the optical signal from the DWDM side of the ONS 15200 network, the
CLIP module conve rts th e se lect ed opt ica l sign al to the 1 310 nm w ave len gth re gion an d delive r s it to
the client layer. If the ONS 15200 system is optically protected (that is, th e optical signal is carried on
two routes), the CLIP module selects which optical signal to transfer to the client layer. You can install
a CLIP module in either the ONS 15252 Multichannel Unit (MCU) or the ONS 15201 Single-Channel
Unit (SCU).
When the CLIP modules are not installed, attach front covers for elec tromagnetic compatibility and
electromagnetic interference (EMC/EMI) precautions.
Release 1.1 provides a new CLIP module that incorporates both clocked (3R) and unclocked (2R) data
regeneration. You can set the mode of operation (2R or 3R) usin g th e m anag emen t int erf ace s. T he new
2R/3R CLIP is fully compatible with the existing 3R CLIP. The 2R/3R CLIP is user configurable for
unprotected or fib er prot ecte d opera tio n.
In addition, Release 1.1 provides two dispersion tolerances: 1800 ps/nm at 0 and 7 dBm, and 3000 ps/nm
at 0 dBm.

5.4 Network Adaptation Module
The NAM splits the ou tgoi ng optica l si gnal from t he CL IP m odu le (o ne of t he D WD M wa vele ngths o r
channels) before tr ansfe rr ing it t o the pa ssive op tical she lf (l ocat ed in the lowe r part of the O NS 15252
MCU). The NAM split ratio can be 100/0, 90/10, 50/50, 10/90, or 0/100. Unprote cted channe ls use the
split ratios 100/0 and 0/100. Protected channels use the split ratios 90/10, 50/50, and 10/90.
The NAM transfers the signal to the passive optical shelf in the following patterns:
• A side or B side (unprotected channel)
• A side and B side (protected channel)
The HFMs collect the inc oming opt ical signa ls from the DWDM side of the ONS 1520 0 system and
transfer the outgoing signals t o the DWDM side of the ONS 15200 syste m. The NAMs the n transfer
these incoming/outgoing optical signals to/from the CLIP modules.
5.5 Network Control Board Module
The NCB module is the hardware platform for the Subnetwork Manager (SNM) software package, which
you access using t he E ther net conn ect or on t he f ron t of the NC B m odu le. T he N CB super vis es,
administers, and monitors the ONS 15200. In addition to controlling all of the ONS 15200 system CLIP
modules, the NCB module collects information about system status, alarms, parameters, and actions on
the internal data bus. You can also store performance monito ring data on the NCB an d upload the da ta
to external media.
Network Adaptation Module
Release 1.1 supports multiple NCBs on the CAN bus; ho wever , y ou can only configure two active NCBs
as managers of any CLIP in a networ k. Any NCB in a netw ork that is no t provisione d as an act ive
manager of a CLIP can still inventory the CLIP. Release 1.0.1 only supports one NCB on the CAN bus.
In addition to alarm lines on the internal data bus, the NCB has three dedicated LEDs. When lit, the
LEDs indicate the status shown in Table 5-2.

The ONS 15200 system can function without the NCB module. Whe n you choose not to use an NCB
module, mount a front cover in its place for EMC/EMI precautions. The front cover used in place of the
NCB module is narrower than the front cover used in place of the CLIP module. Do not interchange the
two types of front co ve rs.

Bridge Module
5.6 Bridge Module
The BM, installed in the passive optical shelf, transfers the remainder of the incoming optical signal
from the A side to the B side and from the B side to the A side. The BM allows the por tion of the optic al
signal that is not intended for the node to bypass the node. If all incoming optical signal wavelengths
terminate at the node, you can us e two Termination modules (TMs) instead of a BM. TMs reduce optic al
crosstalk.
5.7 Collector Filter Module
The CFM combines the functionality of the Hub Filter module (HFM) and the NAM in the ONS 15201
SCU. The CFM transfers optical signals between the DWDM side of the ONS 15200 system and the
CLIP module.
5.8 Connection Module X
Chapter 5 Module Descriptions
The CMX provides a bridge between the A side of one ONS 15252 MCU and the B side of another ONS
15252 MCU. Using a CMX allows you to extend the bandwidth capability of the ONS 15252 MCU
passive optical shelf.
5.9 Connection Module Y
The CMY provides a bridge between the A side of one ONS 15252 MCU and the A side of another ONS
15252 MCU. Alternatively, the CMY provides a bridge between the B side of one ONS 15252 MCU and
the B side of another ONS 15252 MCU. The CMY allows you to extend the bandwidth capability of the
passive optical shelf.
5.10 Dummy Filter Module
The Dummy Filter module (DFM) mechanically stabilizes the optical filter modules. The DFM resides
in the passive op tica l she lf of the ON S 15 252 MC U.
5.11 Dummy Network Adaptation Module

5.12 Hub Filter Module
The HFM filters one wavelength from the incoming DWDM optical signal and transfers the remainder
of the waveleng ths t o sub s eque nt H FM s. Th e HF Ms e ach ad d o ne wa veleng t h to t he o ut going DW DM
optical signal. The HFM is located to the right of the Line module (LM) on the A side of the ONS 15252
MCU and to the left of the LM on t h e B side of the ONS 15252 MCU. The row of HFMs must end with
either a BM, a TM, a CMX, or a CMY.
5.13 Line Module
The LM receives an incoming aggregate optical signal from the DWDM side of the ONS 15200 system
and transfers the outgoing aggregate optical signal to the DWDM side of the ONS 15200 system. A pair
of LMs, one for the A side and one for B side, reside in the passive optical shelf of the ONS 15252 MCU.
The LM contains the monitoring ports for both the incoming and outgoing traffic streams. The split ratio
of the monitoring ports is 10/90. The external interface on the LM can be either an SC or an FC optical
connector.
Hub Filter Module
5.14 Termination Module
Install a TM in the passive optical shelf of the ONS 1 5 252 MCU af ter the you have installed the HFMs.
Insert the TM to the right of the HFMs on the A -side of ONS 152 52 MCU and t o the left of the HFMs
on the B-side of the ONS 15252 MCU in plac e of the BM . The TMs term inate th e optical signal and
improve crosstalk. The TMs can replace the BM when all traffic terminates at the ONS 15252 MCU.
