Custom 25G BiDi SFP28 MODULE, Tailored Simplex
-
Solve Extreme Fiber Scarcity: Specifically engineered for highly dense 5G network rollouts where fiber availability is critical. Achieve 25Gbps bidirectional transmission over a single fiber strand.
-
Distinct Pull-Tab Identification: We manufacture matched pairs with distinct, custom-colored pull-tabs, drastically reducing installation errors and ensuring easy on-site identification for your technicians.
-
Bespoke WDM Wavelength Pairings: We offer fully customized TX/RX frequency combinations to seamlessly integrate into your specific bidirectional overlay infrastructure.
Product Overview
Rolling out dense 5G networks quickly exhausts available dark fiber. Laying new conduit is simply too slow and expensive. The Wolon Custom 25G BiDi SFP28 MODULE provides an immediate, highly strategic workaround. By deploying advanced WDM technology inside the transceiver, these "BiDirectional" modules allow a full 25Gbps duplex connection over just one simplex fiber. We build these matched transceiver pairs to your exact architectural specifications, customizing the multiplexing channels and providing intuitive, color-coded pull-tabs to streamline mass field deployments.
Key Features
-
Custom WDM Integration: Internal diplexers are finely tuned to your requested wavelength pairings, cleanly separating upstream and downstream 25G light paths without signal crosstalk.
-
Simplex LC Connector: Streamlines patch panel density and significantly reduces cable tray clutter by requiring only one jumper per link.
-
100% Interoperability: Avoid OEM lock-in. We program our transceivers to perfectly match the handshake protocols of global 5G telecom equipment vendors.

Frequently Asked Questions
Q1: What are the standard wavelengths for 25G BiDi, and must they be purchased in pairs?
A: Yes, BiDi modules must always be deployed in matching pairs. For 5G networks, our most common high-frequency pairings are 1270nm-TX/1330nm-RX (Side A) paired with 1330nm-TX/1270nm-RX (Side B). We utilize distinct color-coded pull tabs to ensure foolproof on-site installation.
Q2: How exactly does using a BiDi module save money on our backbone?
A: Traditional 25G modules require two fiber strands (one for TX, one for RX). Our BiDirectional (BiDi) modules utilize integrated WDM filter technology to transmit and receive simultaneously over a single strand of single-mode fiber, instantly cutting your physical cabling costs and conduit space requirements in half.
Q3: Does the BiDi module use a standard Duplex LC interface?
A: No. Because BiDi modules transmit and receive over just one fiber strand, they are designed with a Simplex LC (single-core LC) interface. This is the most distinct visual difference between a BiDi module and a standard LR module.
Q4: Do you offer private labeling (OEM) for these specialized BiDi modules?
A: Fully supported. As a comprehensive manufacturing facility, we offer end-to-end OEM solutions. This includes deep EEPROM compatibility coding, custom laser engraving on the metal housing, bespoke labels, and dedicated anti-static packaging for your brand.
