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.

Solid 10G DWDM optical transceivers for our local municipal optical network. DDM monitoring calibrated nicely. Shipping took an extra two days due to customs clearance, but hardware quality is top-notch.

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.

Deployed these DWDM 10G SFP+ modules across our LTE cell site backhaul links where equipment resides in exposed pole-mounted cabinets. The build quality on the Duplex LC receptacle and metal housing is rugged and shielded against EMI. We verified line-rate throughput at 10Gbps across multiple 25-38km spans using standard OS2 patch cables. No optical amplification was necessary. Reliable hardware, compliant protocol framing, and accurate telemetry reporting make this module a solid choice for standard network builds.

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 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.
