SRX48 Seris
Product Description
The SRX48 modules are receivers designed to meet or exceed the SO-
NET/SDH optical interface requirements at OC-48/STM-16 (2.488 Gb/s)
data rate. Three performance versions are available which are fully com-
pliant with Short Reach, Intermediate Reach and Long Reach specifica-
tions at 1300 nm or 1550 nm wavelength.
The receiver for the Short Reach and Intermediate Reach version uses
PIN photodiodes. For the Long Reach version, InGaAs avalanche pho-
todiodes (APDs) are used to achieve high sensitivity. The Long Reach
receiver features a low noise GaAs transimpedance IC with AGC capa-
bility to provide an extremely wide dynamic range. The DATA outputs
are differential signals designed to be AC-coupled into 50 ohm load. A
TTL Signal Detect function which indicates loss of optical input and an
analog Received Optical Power Monitor output are also provided.
All receiver modules can be operated with a single +5V supply. The op-
erating temperature range is -40°C to +85°C for the Short Reach and In-
termediate Reach version and 0°C to +70°C for the Long Reach version.
All receivers are housed in a 24-pin dual-in-line metal package with a
fiber pigtail (single mode fiber for Long Reach version and 50/125 μm
multimode fiber for Short Reach and Intermediate Reach versions),
which is terminated with MU, LC, ST, FC or SC connector.
