Specification : TS-S98D017A
November, 1998
1. General
The SDM7128-XC is a fiber optic transceiver module designed for high-speed digital transmission. These prod-
ucts use a 1.3 µm InGaAsP / InP, FP-LD Laser Diode and InGaAsP, PIN-PD Photodiode as a light source and
detector, respectively. The transceiver module is a PC board mountable package with electrical and optical
interfaces. These modules are designed for short reach, intra office applications.
