155Mbps BiDi SFP Optical Transceiver Module

155-5380xCR is a Bi-Directional (BiDi) transceiver module designed for ultra-long reach duplex optical data communications, including Fast Ethernet and 155Mbps SDH STM-1/SONET OC-3 applications. This BiDi SFP module enables transmission over a single strand of single-mode fiber, providing an impressive 80km transmission distance. By utilizing BiDi technology, it allows for the reduction of fiber cabling infrastructure costs by requiring only half the number of fiber cables compared to traditional dual fiber SFP modules.

Key Features:

  • Hot-Pluggable SFP Package: Ensures easy installation and replacement without interrupting network operations.
  • Single LC or SC Connector: Offers flexibility in connection options.
  • Compliance with SFP MSA Standard: Fully compliant with SFP Multi-Sourcing Agreement (MSA) standard specifications for seamless interoperability.
  • Support for 155Mb/s Data Links: Capable of handling data rates up to 155Mbps.
  • Long Transmission Distance: Provides reliable transmission over distances of up to 80km on 9/125µm single-mode fiber (SMF).
  • High-Quality Optical Components: Utilizes a 1550nm DFB laser transmitter and a 1310nm InGaAs PIN receiver for efficient signal transmission and reception.
  • Single +3.3V Power Supply: Requires only a single power source for operation.
  • Low EMI and Excellent ESD Protection: Ensures stable performance and protection against electrostatic discharge.
  • ROHS Compliant and Lead-Free: Environmentally friendly design adhering to industry standards.

Optional Features:

  • Digital Diagnostic Monitoring Interface: Provides additional diagnostic capabilities for monitoring module performance.
