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.

Deployed 50 of these 10G DWDM modules in outdoor cabinets near an industrial park. Ambient temps swing wildly here, but the -40°C to +85°C rating holds up fine — DOM metrics show consistent thermal stability.

We installed 12 of LINK-PP 10G DWDM modules in a utility substation’s outdoor cabinet (ambient swings from -10°C to +55°C). The industrial temp rating held steady — no thermal shutdowns or performance drops. We used them for 10G Ethernet backhaul to our central SCADA system over 38km of buried SMF. The 100GHz ITU grid aligned perfectly with our existing DWDM mux/demux. DOM monitoring helped us catch a dirty connector early. For critical infrastructure where uptime is non-negotiable, this module delivers.

We deployed these in a campus fiber backbone, all channels stable over 35km. TX power sits around +1dBm, RX around -12dBm — right in spec. DOM lets us monitor temp and voltage live, which is a must for our NOC.

If you are running passive multiplexer setups over single-mode fiber, channel accuracy is everything. We populated several C33 100GHz ports using these LS-DW3310-40I DWDM modules. Optical attenuation metrics remained clean across a full 24-hour soak test under max packet loads. The SFP+ MSA compliance ensures physical fit in dense 48-port switch line cards without mechanical binding or thermal crowding. Having functional DDM reading real-time optical rx/tx power levels makes field troubleshooting infinitely faster for our field technicians.

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!
