FEATURES
DESCRIPTION
l 1-Fiber Bi-Directional SFP Optical Transceiver
l Up to 8.5 Gbps Bi-directional Data Links
l Compliant with SFP+ MSA
The SPB-4920LWG series single mode transceiver is small
form factor pluggable module for bi-directional serial optical
data communications such as 8x/4x/2x Fibre Channel by
using 1330 nm transmitter and 1270 nm receiver. It is with
the SFP 20-pin connector to allow hot plug capability.
Digital diagnostic functions are available via an I2C series
bus specified in the SFP MSA SFF-8472. The transmitter
section uses a multiple quantum well 1330 nm DFB laser
and is a class 1 laser compliant according to International
Safety Standard IEC 60825. The receiver section uses an
integrated 1270 nm detector preamplifier (IDP) mounted in
an optical header and a limiting post-amplifier IC.
