Product Description:
The
LNK-CSFP-1Gxx-80 series single mode transceiver is a small form factor pluggable module
for duplex optical data communications such as Gigabit Ethernet
1000BASE-ZX and Fiber Channel 1x SM-LC-L FC-PI. It is equipped with
the SFP 20-pin connector which provides hot plug capability. This
module is specifically designed for single mode fiber and operates
at a nominal CWDM wavelength with 18 center wavelengths available,
ranging from 1270nm to 1610nm, with each step at 20nm.
The transmitter section uses a high quality multiple quantum well
CWDM DFB laser conforming to the International Safety Standard
IEC-60825 and certified as a Class 1 laser. The receiver section
uses an integrated InGaAs detector preamplifier (IDP) mounted in an
optical header and a limiting post-amplifier IC, ensuring an
incomparable performance. Furthermore, this series is designed to
be compliant with SFF-8472.
Features:
The Data-rate of 1.25Gbps operation requires an 18-Wavelength CWDM DFB LD Transmitter which ranges
from 1270nm to 1610nm with a step of 20nm and is compliant with SFP MSA and SFF-8472. It
supports a SONET OC-24-LR-1 as well as performing RoHS and +3.3V single power supply
operations with a Hot-Pluggable SFP Footprint Duplex LC receptacles.
