100G QSFP28 BIDI 40km

The Q28-100G-BD-LU40/LD40 BiDi QSFP28 Transceiver Module is a high-performance optical transceiver designed for bidirectional data transmission over single-mode fiber. It transmits at two key wavelengths, 1304.58nm and 1309.14nm, achieving 100Gbps speeds over distances up to 40 kilometers. Equipped with an LC simplex connector and compliant with QSFP28 MSA standards, this module is used in data centers and telecommunications for efficient, long-distance data transfer. Its QSFP28 form factor ensures compatibility with various network equipment, and it’s hot-pluggable for easy installation and maintenance. Unlike traditional transceivers, which require two fibers, the BiDi QSFP28 consolidates data transfer into one strand, making it ideal for large data centers with extensive cabling needs. The module is also durable and reliable, with digital diagnostics monitoring (DDM) for real-time tracking of temperature, power, and performance metrics. Rigorously tested to meet industry standards, the Q28-100G-BD-LU40/LD40 BiDi QSFP28 offers a cost-effective, high-speed solution for expanding data infrastructure, providing scalability and efficient connectivity.

Notes:

1. The optical power is launched into SMF.
   2. The receiver shall be able to tolerate, without damage, continuous exposure to an optical input signal having this average power level. The receiver does not have to operate correctly at this input power.
   3. Average receive power, each lane (min) is informative and not the principal indicator of signal strength.
   4. Measured with conformance test signal at TP3 using the test pattern PRBS31Q or scrambled idle for stressed receiver sensitivity for the BER= 2.4x10-4.
   5. Measured with conformance test signal at TP3 (see3.11) for the BER specified in IEEE Std 802.3cd clause 140.1.1.
