100G BiDi QSFP28 150m MMF Transceiver: BIDI-100G-QSFP28-150

Our EDGEOPTIC BIDI-100G-QSFP28-150 is a multi-vendor compatible 100G SR-BiDi QSFP28 bidirectional optical module designed for 100 Gigabit Ethernet applications operating over multimode fiber infrastructure with single-fiber connectivity. This quad small form-factor pluggable transceiver utilizes wavelength division to enable full-duplex 100G transmission over a single multimode fiber strand, delivering up to 106.25 Gbps throughput while reducing fiber count requirements by 75% compared to standard SR4 solutions.

The BIDI-100G-QSFP28-150 module operates using bidirectional technology with 850nm wavelength for transmission and 900nm wavelength for reception on the same fiber. Our 100G SR-BiDi QSFP28 transceiver utilizes VCSEL (Vertical-Cavity Surface-Emitting Laser) array for transmission and PIN photodiode array for receiving. This BiDi architecture enables significant fiber infrastructure savings in environments where multimode fiber count is limited or expensive to expand, while maintaining backward compatibility with 40G QSFP BiDi deployments.

Transceiver ensures a 1.9 dB guaranteed optical link budget, which determines the maximum transmission distance. Over OM5 multimode fiber, the transceiver can reach distances up to 150 meters, with reduced distances on OM3 and OM4 fiber types. However, distance is just an indicative parameter calculated for comfort of identification – eventually we calculate distance taking into account minimal optical budget and average attenuation of optical cabling in industry. The single LC connector interface dramatically simplifies cabling compared to MPO-based parallel solutions.

BIDI-100G-QSFP28-150 compatible 100G SR-BiDi module is a hot-pluggable QSFP28 with single LC/UPC connector as the optical interface. The electrical interface conforms to SFF-8636 and SFF-8419 MSA (Multi-Source Agreement) specifications, ensuring compatibility with standard QSFP28 host systems supporting multiple vendor equipment platforms. Our 100G SR-BiDi QSFP28 transceiver can be encoded to be compatible and successfully operate in different 80+ brands of equipment.

The module incorporates DDM/DOM (Digital Diagnostic Monitoring) functionality providing real-time information including transmitted and received optical power levels, module temperature, bias current, and supply voltage. Additionally, the module supports Host FEC (Forward Error Correction) function which helps the receiving side detect and correct bit errors, improving overall link quality. The module operates within a 0 to 70°C temperature range with maximum power consumption of 3.5W.

Standards compliance includes IEEE 802.3bm for 100 Gigabit Ethernet 100GBASE SR-BiDi specification and QSFP28 MSA. The transceiver supports dual-rate operation including 100G Ethernet (103.125 Gbps) and 40G Ethernet (41.25 Gbps), providing flexibility for mixed-speed network deployments. Our 100G SR-BiDi QSFP28 transceiver is CE/RoHS certified, Class 1 FDA and IEC60825-1 Laser Safety Compliant.

Important: BiDi transceivers must be deployed in matched pairs with complementary wavelength configurations. This module (Tx 850nm/Rx 900nm) connects to a complementary module with Tx 900nm/Rx 850nm configuration. Proper pairing ensures correct bidirectional communication over the single fiber strand.

Typical applications include data center environments with limited fiber availability, cable plant upgrades requiring capacity expansion without new fiber installation, and deployments where simplified single-fiber connectivity is preferred over parallel multimode solutions.

Because our focus is providing top quality service, we are performing serious quality checks before delivery of our products. As a result, we do optical parameter measurements, connector cleanliness tests and QSFP28 transceiver EEPROM memory data validation tests.
