What are the exact working wavelengths of the SFP-10G-LR20BD-D transceiver?

This module transmits data at a 1330nm wavelength (TX) and receives data at 1270nm (RX).

Do I need to deploy this BiDi SFP module in identical pairs on both ends of the link?

No, you must pair it with its complementary module (the 1270nm-TX/1330nm-RX model) on the other end to establish a working link.

What type of fiber optic patch cable should be used with the SFP-10G-LR20BD-D module?

It requires a single-mode fiber (SMF) patch cord with a simplex LC/UPC connector.

What is the maximum transmission distance supported by this 10G SFP+ module?

It reliably supports data transmission distances up to 20km over single-mode fiber.

Can this module handle extreme outdoor environments like unconditioned roadside cabinets?

This standard module is rated for commercial temperatures (0°C to 70°C) and is best suited for indoor data centers. For harsh outdoor environments, please select our Industrial-Grade wide temp (-40°C to 85°C) version from our site.

We run a multi-vendor environment with Cisco and Juniper switches. Will this module cause any compatibility errors?

Not at all, as these modules are fully MSA-compliant and support multi-brand firmware flashing. We can custom-code them for your specific switch brands before shipping to ensure seamless plug-and-play operation.

Can I use this 1330nm-TX/1270nm-RX module on both ends of my single fiber link?

No, BiDi technology requires a mismatched pair to function correctly over a single fiber strand. You must pair this 1330nm-TX/1270nm-RX module with its matching counterpart (1270nm-TX/1330nm-RX) at the other end.

Using these for FTTA (Fiber to the Antenna) cell tower backhaul sites. These 1330nm-TX/1270nm-RX modules handle the outdoor environmental variables beautifully inside the street cabinets. SFP+ slot recognized them instantly as generic MSA modules, and they play nice with our devices.

We deployed these 10G SFP+ single fiber SMF modules to connect our primary data center storage array to a backup site across the city. Over an 11-mile dark fiber link, the optical power budget remains well within the safe margin limits. No frames dropped during our heavy midnight SAN replication tasks. Fantastic product for corporate backup infrastructure!

Procured these for an enterprise multi-building network linking our main HQ to the manufacturing plant about 15km away. The SFP+ BiDi 1330nm-TX 20km DOM module works flawlessly alongside its 1270nm-TX counterpart on the other end. No latency spikes, stable jitter, and very low power consumption under heavy loads. Excellent enterprise-grade alternative.

If you are managing a regional wireless ISP network, you know how expensive fiber leasing can be. These 10GbE single-mode bidirectional transceivers saved our budget. They work seamlessly across our routers on the towers. The DOM diagnostic features are highly accurate compared to my handheld optical power meter readings. Will definitely buy more for our upcoming ring expansion!
