It combines a standard duplex LC interface with real-time digital diagnostic monitoring to support high-density optical expansion.
The transceiver features a hot-pluggable SFP+ footprint that enables easy installation without powering down host systems. It strictly complies with the SFP+ MSA standard to ensure broad compatibility with mainstream networking switches and routers.
This DWDM module delivers dedicated 10Gbps data throughput for bandwidth-intensive enterprise and metro access networks. It provides stable line-rate transmission to support aggregation uplinks and dense multiplexing deployments.
Dense Wavelength Division Multiplexing allows multiple data streams to run across a single fiber pair simultaneously. This optical multiplexing capability helps operators significantly expand total link capacity without laying new fiber cables.
Configured for the 100GHz ITU-T grid, the 1531.89nm optical frequency supports dense C-band channel allocation. Excellent spectral accuracy guarantees clean optical separation and stable signal routing across complex multiplexed systems.
Long-distance single-mode fiber links reach up to 80km thanks to a cooled EML transmitter paired with an APD receiver. This robust optical power budget easily overcomes signal attenuation across extended regional network spans.
The duplex LC optical receptacle ensures secure and low-loss physical connectivity with standard patch cords. The compact connector housing fits neatly into high-density front-panel port configurations.
Integrated digital optical monitoring tracks key operating parameters such as Rx/Tx optical power, temperature, laser bias current, and supply voltage in real time. Full compatibility with SFF-8472 digital diagnostic functions simplifies remote network management and fault isolation.

Q: Will dirty fiber end-faces damage the APD receiver on this module? By A***r
A: Dirt particles can scratch the internal receiver lens and cause optical reflections that degrade the high-sensitivity APD. We recommend inspecting and dry-cleaning every LC connector before mating it with the transceiver. By admin
Q: Can this C57 SFP+ module communicate directly with a 10G 80km optic on a different DWDM channel? By E***m
A: No. For a direct point-to-point link or when connected through a DWDM Mux/Demux, both ends must match the exact same wavelength/channel (C57 1531.89nm) to establish connection. By admin
Q: Does hot-swapping this module cause power spikes or disrupt adjacent switch ports? By K***z
A: No, it features standard SFP+ hot-pluggable electrical contacts designed for safe live insertion and extraction. Surrounding ports and switch backplane operations remain completely undisturbed. By admin
Q: What is the total optical power budget available for fiber plant planning? By E***n
A: The optical power budget is approximately 22dB, calculated between the -1dBm minimum TX launch power and the -23dBm receiver sensitivity. Always reserve a 2dB to 3dB safety margin for fiber aging, splicing, and patch points. By admin
