Gigabit Single Mode Single Fiber BiDi SFP Transceiver LC 1490nm/1550nm1.25G Optical Module with DDM
The Gigabit Single Mode Single Fiber BiDi SFP Optical Transceiver Module is engineered for high-speed Gigabit Ethernet transmission over a single optical fiber. Utilizing 1490nm TX /1550nm RX or 1550nm TX /1490nm RX wavelength technology, the module enables bidirectional communication through one fiber strand, significantly reducing fiber deployment costs while maximizing network efficiency.
Designed for 60km and 80km long-distance optical transmission, this SFP module complies with the SFP Multi-Source Agreement (MSA) and IEEE 802.3z Gigabit Ethernet standards. It features an LC simplex optical connector, supports 1.25Gbps data transmission, and is fully hot-pluggable for easy installation and maintenance.
Built with premium DFB laser transmitters and highly sensitive PIN receivers, the module delivers excellent optical performance, stable signal transmission, low bit error rates, and superior reliability. Digital Diagnostic Monitoring (DDM/DOM) allows real-time monitoring of module operating parameters including temperature, voltage, transmit power, receive power, and laser bias current.
Compatible with most major networking equipment brands, the module is widely used in enterprise networks, telecom systems, industrial Ethernet, FTTH, data centers, security surveillance, campus networks, ISP backbone transmission, and long-distance fiber communication.
