No, BiDi modules must always be deployed in complementary pairs. You must pair this Side A module (Tx1270nm/Rx1310nm) with a Side B module (Tx1310nm/Rx1270nm) at the remote end. By

Leasing dark fiber in metropolitan areas is incredibly expensive, so when our business needed to triple its data replication throughput between data centers, renting another fiber pair was cost-prohibitive. Deploying this BiDi single-mode SFP module allowed us to achieve 25Gbps bidirectional speeds over our existing single leased strand. The digital diagnostic monitoring (DDM) proved invaluable during staging, instantly showing us that our patch cord had a speck of dust causing high insertion loss. Once cleaned, RX power stabilized perfectly at -12dBm over our 31km link. (•‿•)✌️

Using these modules for a suburban base station backhaul deployment over a 28km stretch. The 25G BiDi SFP28 40km link budget leaves plenty of margin for splices and patch panels. Latency is virtually non-existent, fully matching eCPRI protocol specifications. Will definitely order more bulk batches for our phase 2 network rollout next quarter.

Yes you can get this item for much cheaper elsewhere but who knows what kind of quality you\'re gonna be getting. And replacing that part and dealing network problems from low quality parts will cost you much more in the long run.

We managed to consolidate our sprawling multi-building university network core by migrating our primary backbone links to these 25G single-fiber bidirectional transceivers. By upgrading from older 10G duplex setups to 25G BiDi on a single strand, we effectively reclaimed dozens of dark single-mode fiber pairs to use for an isolated research network. The 1270nm-TX and 1310nm-RX channel grouping provides an incredibly clean signal isolation over our 32km intramural spans with zero cross-talk detected during peak student traffic hours. The premium build quality of the pull-tab release latch makes hot-swapping incredibly reliable.

Excellent optical power budget and low attenuation! Tested on an optical time-domain reflectometer (OTDR) before live deployment. The laser output on 1270nm is remarkably stable. Over a 32km span with three patch panels, we still have about 4dB of operating margin left. The APD receiver sensitivity on these 25G SFP28 BiDi modules is top-tier.
