Does the LS-BL273310-20C require a specific module for the opposite end of the fiber link?

Yes. As a BiDi module, it must pair with a transceiver featuring complementary wavelengths, specifically a TX 1330nm/RX 1270nm 10G 20km SFP+ module, to establish a functional optical link.

Can this commercial-grade transceiver be deployed in unconditioned outdoor cabinets?

No. This module is rated for commercial operating temperatures between 0°C and 70°C. For unconditioned outdoor environments, an industrial-grade version (-40°C to 85°C) should be utilized.

What type of fiber optic patch cable is required for this module?

It requires a Simplex Single-Mode Fiber (SMF) patch cable terminated with a standard simplex LC/UPC connector. Dual-fiber (duplex) cables or APC angled connectors are not compatible.

Does this transceiver support multi-vendor switch architectures?

Yes. The module complies with SFP+ MSA specifications and features fully compatible EEPROM coding, enabling seamless operation across major industry-standard enterprise networking platforms.

Hey, does this 10g bidi module work out-of-the-box with Cisco Nexus switches for eCPRI protocols? Don't want to flash EEPROM myself.

Yes! It is fully SFP+ MSA compliant with pre-coded EEPROM. It works seamlessly with major multi-vendor equipment like Cisco Nexus and natively supports eCPRI/CPRI for base station and enterprise setups.

I’m planning a campus network upgrade. Can I use dual-fiber patch cables with this, or does it strictly need a simplex connection?

This is a BiDi (Bidirectional) transceiver, meaning it transmits and receives over a single fiber strand. Therefore, it strictly requires a Simplex LC Single-Mode Fiber (SMF) patch cable. Standard duplex cables are not compatible.

Our data center needs about 300 pieces of this 1270/1330nm transceiver. Do you offer batch discounts for bulk enterprise purchases?

Absolutely! We offer tiered pricing and excellent discounts for enterprise bulk deployments. Please reach out to our sales team directly, and we will provide a custom discounted quote to support your large-scale network deployment.

We need to deploy these in unconditioned outdoor cabinets. Will this 0-70°C commercial version survive, or is there an industrial grade option?

For unconditioned outdoor cabinets, we highly recommend purchasing the industrial-grade version (LS-BL273310-20I) which supports wide-temp operations from -40°C to 85°C. This commercial LS-BL273310-20C model is strictly rated for indoor or temperature-controlled 0°C to 70°C environments.
