SFP 1550DFB Laser 40KM 1000BASE Fiber Optic Module SM BIDI Single Mode
PRODUCT DESCRIPTION
The SFP Module compliants with Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472. The fully SFP compliant form factor provides hot pluggability, easy optical port upgrades and low EMI emission.
1.25Gbps SFP BIDI 40KM Optical Transceiver Module is small form factor pluggable module for bi-directional serial optical data communications such as STM-8, OC-24,Fiber Channel, It is SFP 20-pin connector to allow hot plug capability. This module is designed for single mode fiber and operates at a nominal wavelength of 1550nm.
1.25Gbps SFP BIDI 60KM 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 DFP laser and the PIN photo-detector .
