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
l Compliant with Fibre Channel FC-PI-4 800-SM-LC
l Compliant with 4G and 2G Fibre Channel
l Simplex LC Connector
The SPB-4940LG 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. 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.
