Description
DELTA’s SFF Bi-Directional transceiver is
designed for point-to-point Bi-Directional Optical
Network transmission. The module consists
1550nm FP laser, InGaAs PIN, Preamplifier and
WDM filter in a high-integrated optical
sub-assembly, and it receives up to 155Mbps of
continuous data at 1310nm, and transmits
155Mbps of continuous data at 1550nm.
The module is contained in a 2x5 SFF
industry standard package with a SC receptacle
connector, and support LVTTL transmitter disable
input, LVPECL electrical signal Interface and
receiver signal detect output.
