Can I connect two LS-BL273310-10I modules directly to each other?

No. Because this is a BiDi module using a 1270nm transmitter and 1330nm receiver , it must be paired with a complementary transceiver that transmits at 1330nm and receives at 1270nm.

What type of fiber cable and connector does this module require?

The module features a simplex LC receptacle and requires a single strand of single-mode fiber (SMF) for bidirectional transmission.

What is the maximum supported distance for this transceiver?

It reliably supports high-speed data transmission distances up to 10km on standard single-mode fiber.

Does the LS-BL273310-10I support real-time monitoring?

Yes, it features integrated Digital Diagnostic Monitoring (DDM/DOM) compliant with SFF-8472, tracking temperature, voltage, bias current, and TX/RX power.

Can I use this module with a standard 10G SFP+ port on a Cisco Nexus or Ubiquiti EdgeSwitch? Do I need any special coding?

Yes, these are fully MSA compliant and hot-pluggable. They are designed to be compatible with most major brands including Cisco, Ubiquiti, Mikrotik, and Juniper. If you have a specific OEM requirement, let us know and we can ensure the EEPROM is coded correctly before shipping.

We are looking to deploy these in an unconditioned outdoor enclosure. Will the LS-BL273310-10I handle sub-zero winters and high-humidity summers without failing?

Absolutely. This is the industrial-grade version (I-temp), specifically rated for -40°C to +85°C. It’s designed for harsh environments like outdoor cabinets or industrial sites. For high humidity, just ensure your LC connectors are clean and the enclosure is properly sealed against direct water ingress.

Does this SFP+ support CPRI or eCPRI protocols for 5G fronthaul applications?

Yes, the LS-BL273310-10I supports 10.3Gbps data rates and is compliant with CPRI/eCPRI protocols, making it an excellent choice for base station backhaul and fronthaul networking where single-mode fiber efficiency is critical.

We are planning a large-scale data center upgrade. Do you offer volume discounts for bulk orders of 500+ units, and what's the lead time?

We certainly do! For bulk B2B orders, we offer tiered pricing (as seen on our product page). For 500+ units, please contact our sales team directly for a custom quote. We usually keep significant stock, so lead time is typically 3-5 business days for large batches.

I noticed this is a BiDi module. Do I need to buy two of the same model (LS-BL273310-10I) for a single link?

No, BiDi links require a matching pair with opposite wavelengths. You need one 1270nm-TX/1330nm-RX module (this one) at one end, and its mate, the 1330nm-TX/1270nm-RX module (LS-BL332710-10I), at the other end to establish the link over a single fiber strand.
