H3C QSFP-40G-LR4L-WDM1300 40GBASE-LRL4 QSFP+ 1310nm 2km LC Single-Mode Optical Transceiver Full Datasheet

Basic Parameter Table

Core Product Features

1. Original H3C 40G short-reach single-mode QSFP+ LR4L optical module, fully compatible with H3C S10500/S12700 series 40G data center core switches.
2. Complies with 40GBASE-LRL4 QSFP+ MSA standard, integrates 4-channel 1310nm CWDM wavelength division multiplexing, 4 independent 10G lanes multiplexed over a pair of single-mode fiber, stable 2km transmission.
3. Built-in full DOM digital monitoring circuit, real-time monitoring of each channel Tx/Rx optical power, supply voltage, internal temperature, laser bias current for independent lane fault diagnosis.
4. Standard hot-swappable plug-and-play QSFP+ design with blue pull tab, no equipment power-off required during replacement, simplifies data center cabinet maintenance.
5. All-metal sealed housing with integrated heat sink, excellent heat dissipation and anti-electromagnetic interference performance, suitable for high-density leaf-spine data center deployment.
6. Low-cost short-distance 40G single-mode interconnection solution, ideal for intra-data center cabinet-to-cabinet short fiber links.

Typical Application Scenarios

1. Data center leaf-spine architecture 40G inter-switch uplink within 2km single-mode fiber coverage.
2. Server rack aggregation switch 40G uplink short-distance convergence.
3. High-performance computing (HPC) cluster internal 40G fiber interconnection.
4. Not applicable for multi-mode short-reach transmission, long-distance 10km+ LR4 modules, 100G high-speed transceivers.
