FAQ About SFP+ LR Optical Transceiver

Does the 10G LR transceiver support Digital Diagnostic Monitoring (DDM)?

Yes. It implements SFF-8472 DDM functionality, allowing real-time monitoring of Tx/Rx optical power, temperature, laser bias current, and supply voltage via compatible switch CLI or SNMP .

Is the 10G SFP+ LR optical transceiver compatible with equipment?

This hot-pluggable 10G SFP+ module is tested to meet SFP+ MSA and IEEE 802.3ae 10GBASE-LR standards, ensuring seamless interoperability with Cisco Nexus/Catalyst, Juniper EX/QFX, Huawei S series, and other major 10 GbE platforms .

What operating temperature range does the 10G LR optical transceiver support?

Designed for standard commercial environments, this LR transceiver operates between 0 °C and +70 °C, making it suitable for data center and enterprise backbone applications .

Which fiber patch cables are recommended for use with the 10G optical transceiver ?

Use LC-LC single-mode fiber patch cords compliant with ITU-G.652. Yellow-jacketed cables with low insertion loss (< 0.3 dB) help maintain signal integrity over 10 km links .

  1. Inspect and clean fiber endfaces with isopropyl alcohol and lint-free wipes.

  2. Check DDM readings for Tx/Rx power; ensure Rx power > –14 dBm.

  3. Verify fiber length and splice/bend loss.

  4. Swap with a known-good LR module to isolate faults.
    These steps address common causes of BER and link flaps .
