STM-1 Optical to STM-1 Electrical
Converter
Product
Overview
Orion
Telecom Networks Inc. offers STM-1
Optical to STM-1 Electrical converter provides a simple
and cost-effective conversion between STM-1 optical
interface and STM-1 electrical interface. STM-1 Optical
to STM-1 Electrical converter is an interface conversion
equipment supplied with one STM-1 electrical (75 Ohms
BNC) interface and one STM-1 optical (MSA compliant SFP)
interface.
1+1, STM-1 Optical to STM-1 Electrical converter option
is also offered and available.
STM-1 Optical to STM-1 Electrical converter is a compact
solution housed in a 1U high (44mm), 19-inch
rack-mountable shelf, which can be installed in any
DIN-standard 19-inch rack.
This unit offers five power supply
options. Options for the power supply to the equipment
include:
a) 110~240 VAC 50/60 Hz plus -48V DC Inputs (range
-18V DC~-72V DC), for power
redundancy.
b) Dual DC - 48V Inputs (range -18V DC ~ -72V DC), for
power input redundancy.
c) Dual AC 110V AC to 240V AC, 50 / 60 Hz Inputs, for
power input redundancy.
d) Single AC 110V AC to 240V AC, 50 / 60 Hz Inputs.
e) Single -48V DC (range -18V DC ~ -72V DC) Input.
