Is this transceiver compatible with multi-mode fiber? Also, what type of interface connector does it use?

This 10km optical module is explicitly engineered for Single Mode Fiber (SMF) only and will not work over MMF. It utilizes a Simplex SC connector, which is the industry standard for fast, efficient, single-strand optical routing.

Does this Gigabit Ethernet transceiver meet standard industry regulations and safety compliances?

Yes, it is fully MSA (Multi-Source Agreement) compliant, supports the SFF-8472 standard for real-time DOM/DDM monitoring, and adheres strictly to CE, FCC, and RoHS international networking and environmental standards.

My outdoor telecom cabinets get super hot during the summer. Can this 0-70°C module survive, or do you have an industrial version?

This specific module is engineered for standard commercial indoor temperatures (0 to 70°C). For harsh outdoor environments like exposed base stations, we highly recommend purchasing our industrial-grade version, the LS-SC31551G-10I, which easily handles extreme wide temperatures from -40°C up to 85°C.

Will this BiDi SFP play nice with my mix of Cisco and Ubiquiti switches?

Yes! The LS-SC31551G-10C is highly OEM compatible. It’s been thoroughly field-tested in multi-brand environments, ensuring seamless plug-and-play interoperability across Cisco, Ubiquiti, Mikrotik, and other major networking vendors without throwing any compatibility errors.
