Does this optical transceiver support CPRI or eCPRI protocols for cellular LTE backhaul links?

Yes, this LS-DW3310-40I DWDM module supports line rates up to 10.7Gbps, making it ideal for LTE optical links, CPRI/eCPRI, and standard 10G Ethernet.

Can we use this 10G SFP module directly with our existing 100GHz C-band passive DWDM Mux/Demux gear?

Absolutely. It operates specifically on DWDM Channel C33 (1550.92nm), making it fully compatible with standard 100GHz ITU C-band passive multiplexers.

Can I plug this 10G SFP+ optical transceiver into an existing OM4 multi-mode fiber patch panel?

No, this DWDM module requires single-mode fiber with duplex LC connectors to work properly over distance.

Audited the LS-DW3310-40I 10G SFP+module using our optical spectrum analyzer and BER test set. The C33 1550.92nm wavelength grid accuracy is strictly maintained within 100GHz spacing limits. Transmitter output power and PIN receiver sensitivity hit right in the sweet spot for our 36km single-mode link, yielding an operational link budget margin of over 3.5dB. Real-time digital optical monitoring parameters map accurately via standard SFF-8472 registers. Excellent physical layer reliability for demanding telecom infrastructure.

Ordered 40 of these DWDM modules for a 10G Ethernet backhaul project. The 100GHz grid spacing matched our existing DWDM mux perfectly. No handshake issues, no flapping. For the price, this is a no-brainer for metro builds.

We needed a cost-effective C33 1550.92nm 100GHz DWDM transceiver for a regional backhaul link upgrade. The LS-DW3310-40I pulled the link immediately on both ends of our 32km SMF span. Signal margin is well within specs!
