PRODUCT DESCRIPTION
This module is designed to be compliant with SFF-8472 SFP
Multi-source Agreement (MSA)
An optical module, also called fiber optic transceiver or optical
transceiver, is a typically hot-pluggable device used in
high-bandwidth data communications applications. Transceiver
modules typically have an electrical interface on the side that
connects to the inside of the system and an optical interface on
the other side that connects to the various devices through a fiber
optic cable. An optical module functions as a photoelectric
converter which converts the electrical signal into light and vice
versa.
1.25Gb/S SFP Duplex Optical Transceiver Module Small Form Factor Pluggable (SFP) transceivers are compatible with
the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). The
transceiver consists of five sections: the LD driver, the limiting
amplifier, the digital diagnostic monitor, the FP laser and the PIN
photo-detector .The module data link up to 20KM in 9/125um single
mode fiber.
The transmitter section uses a multiple quantum well laser and is a
class 1 laser compliant according to International Safety Standard
IEC-60825. The receiver section uses an integrated InGaAs detector
preamplifier (IDP) mounted in an optical header and a limiting
post-amplifier IC.
