Features

WFB5351099-ECL

The 1.25G SFP BiDi 10km LC single mode transceiver provides digital diagnostic information of its operating conditions and status, including transmitting power, laser bias, receiver input optical power, module temperature, and supply voltage. Calibration and alarm/warning threshold data are written and stored in internal memory (EEPROM). The memory map is compatible with SFF-8472, as shown below. The diagnostic data are raw A/D values and must be converted to real world units using calibration constants stored in EEPROM locations 56 – 95 in A2h.

1. Up to 10km on 9/125um SMF

The 1.25G SFP BiDi 10km LC single mode delivers robust optical performance supporting transmission distances up to 10km over standard 9/125μm single-mode fiber. This extended reach capability makes it an ideal solution for campus backbone links, metro access networks, and long-distance interconnectivity between distributed facilities. Count on stable, high-quality signal integrity across the entire link span, ensuring your data arrives reliably at its destination every time.

2. Supports up to 1.25Gb/s data rates

The 1.25G SFP BiDi 10km LC single mode transceiver supports 1.25Gb/s high-speed connectivity, unleashing the full potential of your gigabit network infrastructure. Experience buffer-free video conferencing and instantaneous data access, empowering your business with reliable, future-ready performance.

3. Single Mode LC Connector SFP Transceiver

The 1.25G SFP BiDi 10km LC single mode transceiver engineered with a single-mode LC interface to maximize signal integrity over extended distances. This connector type minimizes insertion loss and back reflection, preserving optical power for reliable 10km+ transmissions. The result is a robust, high-performance link that you can count on for demanding campus and metro networks.

4. Operating Case Temperature

Designed to perform in a broad range of environmental conditions, this SFP transceiver is available in two temperature grades to suit your deployment needs. The Commercial version operates from 0 to +70°C, making it the perfect choice for standard indoor environments such as data centers and telecom rooms. For extreme outdoor or industrial settings, the Industrial variant withstands -40 to +85°C, delivering unwavering reliability even in the harshest conditions.
