10G SFP+ BiDi 1270/1330 Optical Transceiver Module
Product Overview
The Apex 10G SFP+ BiDi module carries one 10 Gigabit link over a single strand of fiber. The transmitter runs at 1270nm and the receiver at 1330nm, so a working link is built from two matched parts: one 1270nm TX / 1330nm RX unit and its partner at 1330nm TX / 1270nm RX.
Because each direction gets its own wavelength instead of its own fiber, a BiDi link uses one simplex LC run instead of a duplex pair. That is why 10G BiDi is the usual answer when a 10G service has to be delivered over the single spare strand left in a duct, a street cabinet or an existing FTTH cable, and why access and metro operators keep it in the spares kit next to the duplex parts.
Every unit is burnt in and tested for optical power, extinction ratio and error rate, reports live readings through the DDM interface, and is coded for the switch, OLT or router platform you name before it leaves the warehouse. Reach options cover 10km, 20km and 40km on standard single mode fiber, with 60km and 80km builds on request.

Applications
Access and Metro Single Fiber Runs
Delivers a 10G service over the one spare strand in a duct or cable where pulling a second fiber is not economic.
FTTH and PON Backhaul
Upgrades an OLT uplink or a PON backhaul segment to 10G on the fiber that is already in the ground.
Campus and Industrial Links
Connects buildings, cabinets and outdoor sites at 10G when only one strand of the campus cable is available, with industrial temperature versions for unheated cabinets.
Compatibility
10G BiDi modules are coded to the host platform you specify, including carrier Ethernet switches, OLT equipment, routers and media converters, and are tested on live ports before shipment. Because a BiDi link only comes up when both ends match, we quote the module as a pair and label each unit A or B so field teams cannot fit two identical units by mistake.

Frequently Asked Questions
What does 1270/1330 TX/RX mean on a 10G BiDi module?
It means the transmitter works at 1270nm and the receiver at 1330nm. The module at the far end is the opposite type, 1330nm TX and 1270nm RX, so both directions travel on the same strand.
Can I use two identical 10G BiDi modules on one link?
No. Two 1270/1330 units have no receiver for each other's wavelength. Order the pair, or check the wavelength printed on the existing unit and match it with the opposite type.
Which reach should I choose for a single fiber 10G link?
Measure the span and add margin. 10km suits campus and access runs, 20km and 40km cover metro spans, and 60km or 80km builds are available where the route is longer.
Are 10G BiDi modules in stock?
Yes. The 10km, 20km and 40km pairs are held in stock and quoted the same day, with longer reaches built to order.
