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.
