2262 T1/E1 Fiber Optic Modem Canoga Perkins
1. Description
1.1 2262 Modem
The 2262 T1/E1 Fiber Optic Modem features standard data speeds of 1.544Mbps
(T1) or 2.048Mbps (E1).
Available as a stand alone or rack-mount unit, the 2262 has local and remote
loopback capability for system diagnostic test. A set of alarm relay connectors
(Normally Closed and Normally Open) is provided to indicate optical link and power
status. Input power can be 115 or 230VAC (+/−10%), or an optional -48VDC.
Connectors can be either:
• T1 DA-15/RJ-48C or Terminal Block/RJ-48C
• E1 Terminal Block and BNC
The 2262 has extended distance options. Transmission distances to 40km or more
are realistic when using single mode optics. The 2262 is typically offered for
multimode fiber optic applications at 850nm, but also has the option of 1310nm
single mode.
The 2262 is transparent to the incoming bipolar signal and is fully compatible with
allowed speed variations. It allows the passing of bipolar violations for B8ZS
coding for T1 or w for E1.

1.2 Applications
Applications for the 2262 are numerous and varied. For example, it can be used for
earth station down links, fiber front ends for T1/E1 multiplexers, PBX interconnects
or linking CAD/CAM displays to controllers (see Figures 1-1 and 1-2).

2. Installation
2.1 Unpacking the Unit
Each 2262 modem is factory tested and shipped in protective cartons. After
unpacking the unit and accessories, retain the shipping carton and protective
packing for reuse in the event a need arises for returning it to the factory.
To assure proper operation of the modem, please inspect it and its shipping carton
carefully for damage. If damage is sustained to the unit, file a liability claim immediately with the freight carrier. Canoga Perkins is not liable for damage caused during
shipment.
2.2 General Installation
2.2.1 Manufacturing Settings
The 2262 has the following settings from the factory:
• Switchable AC Power Setting: 230VAC
• Input DC Power Option: -48VDC
• Impedance Option (E1 only): 75Ω (Up position for Rack Mount Card)
• Loopback Switch: OFF
2.2.2 Fiber Cable
The proposed fiber optic cable must provide adequate bandwidth and optical loss
characteristics for the intended modem link. The 2262 is compatible with 8-10/125
single mode and 62.5/125 multimode cables.
The connectors are clearly marked, either transmit (Tx) or receive (Rx), on the back
panel of stand alone units and on the rear of the 2201 Rack Chassis.
For multimode applications, the 2262 is available with ST* connectors. For single
mode applications, the 2262 is available with FC or ST* connectors.
Warning: Do not over tighten FC/PC fiber connections - damage may
occur. Hand tighten only!
*ST is a Trademark of AT&T.
