Is this 1310nm-TX/1550nm-RX module fully MSA compliant and does it support standard Gigabit Fibre Channel?

Yes. It is fully MSA (Multi-Source Agreement) compliant, ensuring universal form factor and signaling alignment. It also natively supports both Fast Ethernet and Gigabit Fibre Channel protocols for heavily regulated network environments.

Just to clarify for my installation crew, does this module take multimode or single-mode fiber, and what connector type is required?

This transceiver is designed exclusively for Single-Mode Fiber (SMF). Your field crew will need to use fiber patch cables with a Simplex LC connector to link up properly.

We run a mixed environment with Cisco Catalyst and Juniper EX series switches. Will this 1G BiDi SFP 40km module interoperate without throwing "unsupported transceiver" errors?

Yes, absolutely. The LS-BL31551G-40C features widespread OEM compatibility and is heavily tested for multi-brand interoperability. It will sync natively with both Cisco and Juniper switches right out of the box.

Our data center needs to batch deploy around 500 units for a massive campus networking upgrade. Do you offer volume discounts for enterprise procurement?

We definitely do. For bulk orders of 500 units or more, our tier-based pricing kicks in, reducing the unit cost significantly. Please reach out to our B2B sales team to get a formalized quote with the exact discount applied.

I use this simplex LC optical transceiver for remote base station backhaul. Even near the 70°C upper limit in summer, the DOM feature shows zero optical power degradation. Highly recommended.
