What specific wavelengths does this BiDi module use?

It transmits signals at a 1270nm wavelength and receives signals at 1330nm.

What is the connector type required for the optical fiber patch cable?

This transceiver is equipped with a simplex LC receptacle for secure single-port fiber connection.

Can this transceiver work in extreme outdoor temperatures?

Yes, this industrial-grade module operates reliably within a wide range of -40°C to +85°C.

Does the LS-BL273310-40I require dual fibers for communication?

No, it utilizes BiDi technology to enable full-duplex data links over a single fiber strand.

I'm planning a large-scale Metropolitan Area Network (MAN) deployment and need about 200 of these 40km transceivers. Is there any discount for bulk procurement?

Absolutely. For wholesale datacenter and ISP bulk deployments, we offer tiered pricing. Since you're looking at 200 units, you'll easily qualify for a B2B volume discount and free shipping. Just drop our sales team an email or use the live chat to get a custom quote!

We run a mixed environment with Cisco Catalyst and Arista switches. Do I need to buy different coded versions for this 10G SFP+ BiDi module?

No, you don't! The LS-BL273310-40I supports multi-vendor OEM compatibility out of the box. We’ve thoroughly verified its seamless plug-and-play operation across Cisco, Arista, Juniper, and other major platforms without triggering unsupported transceiver errors.

We are upgrading our LTE base station backhauls and the outdoor enclosures get extremely hot in the summer. Can this module survive without AC?

Yes, it is purpose-built for harsh edge environments. This is a true industrial-grade optical module operating safely between -40°C and +85°C. You’ll have no problem running it in un-AC’d outdoor cabinets, factory floors, or cell tower deployments.

Does the DDM/DOM interface support advanced telecom standards like CPRI and OBSAI for our radio access network?

Yes, it does. Aside from standard IEEE 802.3ae and 10GBASE-LR/LW, this module fully supports CPRI and OBSAI protocols. The real-time DOM ensures you can accurately monitor TX/RX power, bias current, and temperature remotely across your entire telecom routing infrastructure.
