AND

CANADIAN DEPARTMENT OF COMMUNICATIONS

RADIO FREQUENCY INTERFERENCE STATEMENTS

This equipment generates, uses, and can radiate radio frequency energy and if
not installed and used properly, that is, in strict accordance with the
manufacturer’s instructions, may cause interference to radio communication. It
has been tested and found to comply with the limits for a Class A computing
device in accordance with the specifications in Subpart J of Part 15 of FCC rules,
which are designed to provide reasonable protection against such interference
when the equipment is operated in a commercial environment. Operation of this
equipment in a residential area is likely to cause interference, in which case the
user at his own expense will be required to take whatever measures may be
necessary to correct the interference.

Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.

This digital apparatus does not exceed the Class A limits for radio noise emission
from digital apparatus set out in the Radio Interference Regulation of the
Canadian Department of Communications.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant
les limites applicables aux appareils numériques de la classe A prescrites dans le
Règlement sur le brouillage radioélectrique publié par le ministère des
Communications du Canada.

CERTIFICATION NOTICE FOR

EQUIPMENT USED IN CANADA

The Canadian Department of Communications label identifies certified
equipment. This certification means that the equipment meets certain
telecommunications-network protective, operation, and safety requirements. The
Department does not guarantee the equipment will operate to the user’s
satisfaction.

Before installing this equipment, users should ensure that it is permissible to be
connected to the facilities of the local telecommunications company. The
equipment must also be installed using an acceptable method of connection. In
some cases, the company’s inside wiring associated with a single-line individual
service may be extended by means of a certified connector assembly (extension
cord). The customer should be aware that compliance with the above conditions
may not prevent degradation of service in some situations.

Repairs to certified equipment should be made by an authorized Canadian
maintenance facility—in this case, your supplier. Any repairs or alterations made
by the user to this equipment, or equipment malfunctions, may give the
telecommunications company cause to request the user to disconnect the
equipment.

Users should ensure for their own protection that the electrical ground
connections of the power utility, telephone lines, and internal metallic water pipe
system, if present, are connected together. This precaution may be particularly
important in rural areas.

CAUTION:

Users should not attempt to make such connections themselves,
but should contact the appropriate electric inspection authority,
or electrician, as appropriate.

The LOAD NUMBER (LN) assigned to each terminal device denotes the
percentage of the total load to be connected to a telephone loop which is used by
the device, to prevent overloading. The termination on a loop may consist of any
combination of devices, subject only to the requirement that the total of the load
numbers of all the devices does not exceed 100.

2. Introduction

2.1 Product Overview

The CampusLIGHT Fast Ethernet Fiber Extender (LCL114A) is designed for
100BaseTx to multimode or single-mode fiber conversion. When used in point­to-point full duplex connections, the LCL114A Fiber Extender extends the
distance of Fast Ethernet networks up to 2km using multimode fiber or up to
60km using single-mode fiber. It can be used for links between switches/routers,
stations and servers.

The LCL114A features RJ45 connectors, multimode SC and ST, and single­mode SC connectors to provide the copper to fiber interfaces.

The LCL114A is rackmountable in the LCL100-RACK and RM510 rackmount
frames that support either 110/220V AC or 48V DC power supplies.

2.2 Features

2.2.1 Drive Distances

Single-mode
A fiber optic link of up to 60km over single-mode fiber is achievable between
LCL114A Fast Ethernet Extenders using the High Power option SC optics which
provide 30dB optical budget. The Standard Power option provides 19dB optical
budget and will support 40km.

Multimode
A fiber optic link of up to 2km over multimode fiber is achievable using either ST
or SC optics which provide 11dB of optical budget.

See Specifications for details.

2.2.2 Ergonomics

The LCL114A is packaged in a small freestanding case (118mm x 75mm x
25mm, L x W x H) complete with rackmount ears. This configuration allows the

LCL114A to be rackmounted in a 19

" rack using the LCL100-RACK and RM510

rackmount frames.

The LCL100-RACK supports up to 4 CampusLIGHT

 units in a 1U high 19"

frame and the RM510 supports up to 16 units in a 3U high 19" frame. For wall
mounting a bracket that holds the LCL114A and its power supply is available,
order code LCL100-WALL.

2.2.3 Power Supply

The LCL114A can be powered either from a small external power supply or from
a 3U high rackmounting power supply capable of supporting 14 devices. Two
variants are available: 90-264V AC (PS500) and 48V DC (LCL100-PS48).

Note:
Units ordered for use with the rackmounting power supply will not contain a
separate power supply; this must be ordered separately.

3. Connectors & Cables

3.1 100BaseTx RJ45 Connectors

Two RJ45 connectors are provided on the LCL114A for 100BaseTx connection.
One is a standard straight-through MDI jack labelled “II” and the other is the MDI­X jack labelled “X” which provides an internal crossover function.

6 Tx- Rx-

Only one jack can be selected for the 100BaseTx interface. This design allows
you to simplify connections to any remote device using a standard straight­through UTP cable without the need for a crossover cable. Just make sure the
“X-to-II” connection rule is followed.

3.2 100BaseTx UTP Cable

Cable: Category 5 UTP
Maximum Cable Distance: 100 meters (328 feet)

3.3 Fiber Optic Connectors

Two fiber optic connectors are provided for fiber optic cable connection. One is
labelled “Tx” for transmitting operation and the other is labelled “Rx” for receiving
operation.
