Can the D-Link DEM-310GT Compatible LINK-PP be monitored remotely?

Yes. DOM enables live monitoring of optical power, voltage, and temperature.

Why choose the 1310nm wavelength?

It supports efficient transmission on single-mode fiber and is widely used for reliable 1G links.

What are its typical use cases?

Enterprise networks, campus backbones, telecom access, FTTx, and other gigabit optical links.

Does it support standard Gigabit Ethernet protocols and optical diagnostics?

Yes. The module supports IEEE 802.3z, IEEE 802.3ah, SFP MSA (INF-8074i) and SFF-8472 DOM/DDM, allowing real-time monitoring of transmit power, receive power, temperature, voltage and laser bias current on supported networking equipment.

What type of fiber and connector should I use with this module?

This model is designed for single-mode fiber (SMF) with a Duplex LC/UPC interface. It operates at 1310nm and supports transmission distances up to 10km under standard optical link conditions.

Is there an industrial temperature version for outdoor cabinets or base station deployments?

Yes. If your project requires extended operating temperatures for industrial or outdoor environments, we also provide industrial-temperature versions. Contact our sales team with your environmental requirements for the appropriate recommendation.

We're planning a project with 300+ units. Do you offer better pricing for bulk orders?

Yes. Volume discounts are available for enterprise and distributor purchases. Please send us your required quantity and destination country, and we'll provide a customized quotation with the best available pricing.

Will this module work with Cisco, Juniper and HPE switches, or is it vendor locked?

The LS-SM311G-10C is designed as an MSA-compliant compatible SFP transceiver and is widely compatible with Cisco, Juniper, HPE, Dell, Arista, Netgear and many other Gigabit Ethernet switches. If you have a specific switch model, feel free to contact us for compatibility verification before ordering.

We installed twenty of these 1310nm 10km SFP modules across a campus fiber network replacing aging optics. Every unit came online immediately and DOM statistics matched our expectations. Power levels stayed consistent after several days of continuous traffic. Definitely a dependable option for enterprise Gigabit Ethernet. ^_^
