1G BiDi SFP

1G BiDi SFP

Shop LINK-PP compatible 1G BiDi SFP modules for simplex LC single-mode links that reclaim a fiber strand. This niche store groups BX upstream/downstream pairs (commonly 1310 nm TX / 1490 nm RX and the mate 1490/1310)—EEPROM-coded for Cisco, Juniper, HPE, and other major platforms. Return to 1G SFP for duplex SX/LX grey optics, or the parent optics hub for other rates. Always order matching U/D mates and confirm TX/RX direction, simplex LC polish, reach, and DOM on each product page before ordering.

Frequently asked questions

01.What is a 1G BiDi SFP and when should I use it?
A BiDi (BX) SFP carries Gigabit Ethernet over one simplex SMF strand by using different TX and RX wavelengths. Use BiDi when fiber count is limited (campus risers, leased dark fiber) and you can install a matching upstream/downstream pair at each end.
02.How do GLC-BX-U and GLC-BX-D (or 1310/1490 pairs) work together?
One end transmits at 1310 nm and receives at 1490 nm (U / “34” style); the mate transmits at 1490 nm and receives at 1310 nm (D / “43” style). Order both directions for every link—two U modules or two D modules will not pass traffic. Confirm wavelength direction on the PDP.
03.Can I mix BiDi with duplex LX or SX optics?
No—BiDi simplex optics need a BiDi peer with the opposite wavelength plan. For standard duplex LC multimode or single-mode, use grey 1G SFP SX/LX modules instead of this BiDi store.
04.Are these 1G BiDi modules coded for Cisco, Juniper, and HPE?
Yes—select the Compatible PN that matches your OEM platform. LINK-PP 1G BiDi SFPs follow MSA specs and are EEPROM-coded for the target brand. Browse the Cisco compatible hub when you already have the OEM part number.
05.Do LINK-PP 1G BiDi optics support DOM?
Most optical 1G BiDi SKUs support digital optical monitoring (DOM/DDM) for temperature, voltage, and Tx/Rx power per the datasheet. Confirm DOM, simplex LC polish, and rated reach on the individual product page before you order.
