Warning

Warning

Class 1 laser product.

Because invisible laser radiation may be emitted from the aperture of the port when no
cable is connected, avoid exposure to laser radiation and do not stare into open
apertures.

Feature Overview

Feature Overview

The Cisco uBR10 Spatial Reuse Protocol (SRP) OC12 single-mode fiber, long reach (SML) dynamic
packet transport (DPT) WAN line card provides shared IP over SONET capability for the
Cisco uBR10012 router platform.

The Cisco uBR10-SRP-OC12SML DPT WAN line card:

• Accommodates large scale network topology.

The WAN card is deployed in SONET OC-12 DPT rings. The DPT rings are connected to SONET
Add Drop Multiplexers (ADMS) allowing the creation of small or very large rings. Each DPT ring
supports a maximum of 64 nodes.

• Leverages fiber optics capacity at OC-12c line rates.

The WAN card has two SC duplex ports. Each SC duplex port provides the physical connection to
an adjacent device in a DPT ring.

• Supports single mode fiber transmissions.

• Allows data to obtain fair-shared access to the OC-12c rings.

• Supports Version 1 SRP Protocol

Attenuation

Note The maximum distance of 40 km assumes that the 1310 nm SMF optical cable attenuation is no more

• Implements protection mechanisms, including wrap and unwrap, in the event of fiber or node

failure.

The Cisco uBR10-SRP-OC12SML DPT WAN line card requires two card slots. For that reason, the card
is normally installed in Slot 2 and Slot 4 if you are using two cards. If you are using only one card than
install the card in Slot 2, Slot 3 or Slot 4. See Figure 1.

The Cisco uBR10-SRP-OC12SML DPT WAN line card is designed to be used at any distance between
15 and 40 kilometers (km). For shorter distance operations (less than 15 km), use a 10 dBm optical
attenuator on the link (see Figure 6 on page 7) between the two nodes to prevent clipping and over
saturation of the optical receiver. The attenuator should be made of a non-metallic or plastic material.

The exact attenuation value is based on the real cable length or the number of couplers and splicers on
the link. For example, 5 dBm attenuator could be used in a 7 km link.

than 0.5dB per kilometer; and that there is no optical coupler or splicer in on the link (each could add

0.5dB loss).

Cisco recommends the use of a SC/PC female to SC/PC male optical attenuator.

Tip The SC/PC (Standard Connector/Physical Contact) denotes a connector with a rectangular shape.

The surfaces are parallel with respect to the port (not angled). SC/APC (Standard Connector Angled
Physical Contact) denotes an angled surface.

Caution Make sure that you obtain the correct connector type (SC/PC) when purchasing optical attenuators.

Angled SC/APC type mating surfaces can damage the Cisco uBR10-SRP-OC12SML DPT WAN line
card (RX port) interface.

Connectors and Cables

Connectors and Cables

The Cisco uBR10-SRP-OC12SML DPT WAN line card uses a single-mode fiber-optic interface cable to
connect the Cisco uBR10012 router to another router or switch. See Figure 6 on page 7.

Table 2 Cable Specification

Fiber Type Wavelength, nm Core Size, microns Cable Distance

Single-mode fiber 1310 8 to 10 49,213 - 131,234 ft.

Single-mode cables are yellow.

Note Single-mode fiber-optic cables are not available from Cisco Systems.

For SONET or SDH single-mode fiber-optic connections, use one duplex SC-type connector (Figure 4)
or two simplex SC-type connectors. See Figure 5.
