# Product Documentation
# Product Description

BIDI-100G-QSFP28-80B is a B side 100G BIDI ZR4 Multi-Vendor MSA Compatible Bidirectional QSFP28 (Quad Small Form-Factor Pluggable 28) Transceiver designed for operation over Single-Mode Fiber (SMF). 100G BIDI ZR4 QSFP28 4WDM hardware building principles are similar as traditional 100G LR4, 100G ER4 modules as it has cooled 4x25Gb/s LAN-WDM NRZ (non return to Zero) modulated, EML lasers, therefore modules can be used in legacy 100G switches and routers and not require PAM4 modulation support or RS (544,514) FEC support to achieve desired distance as it is required by BIDI 100G PAM4 module series. 100G BIDI transceivers are designed for dense applications and provide the ability for operators and service providers to save optical fiber resources. Please note to establish A to B connection this B side BIDI-100G-QSFP28-80B module must work in pair with A side BIDI 100G module BIDI-100G-QSFP28-80A.

100G BIDI ZR4 B side module has a minimum guaranteed optical budget of 30 dB, which in most cases is enough to reach 80km over OS2 single-mode fiber with RS(528,514) FEC enabled on the host device. However, distance is just an indicative parameter calculated for comfort of identification. Eventually we calculate distance taking in account minimal optical budget and average attenuation of optical cabling in industry. BIDI 100G ZR QSFP28 4WDM uses 4 channel 25 Gbps 1295.56nm, 1300.05nm, 1304.58nm, 1309.14nm EML (External Modulation Laser) transmitters and 4 channel 25 Gbps 1273.55nm, 1277.89nm, 1282.26nm, 1286.66nm PIN photodiode receivers. On the transmission side module converts four electrical interface lanes (CAUI-4) 25-Gbps into a four 25-Gbps optical signal (NRZ modulated) and reversely at the receiver side four 25-Gbps optical signals are converted into four 25-Gbps electrical signals. Module supports DDM/DOM optical diagnostics, which provide diagnostic information about the present operating conditions. BIDI 100G ZR QSFP28 4WDM operates in the standard 0°-+70°C temperature range and has a Single LC optical connector and 38 pins edge connector for electrical interface. BIDI-100G-QSFP28-80B supports 103.125 Gbps data rate and such applications as 100G Ethernet.

100G BIDI ZR4 B side module can be used in Cisco, HP, Mellanox, Intel, Arista, Huawei and other industry well known manufacturers equipment. Transceivers are CE/RoHS2.0 certified and are compliant with product safety standards. BIDI-100G-QSFP28-80B transceivers are fully compliant to QSFP28 MSA (Multi Source Agreement), where IEEE 802.3cu defines physical and management layer specifications CAUI-4 electrical interface, SFF-8679 defines QSFP+ 4X Hardware and Electrical Specification. Consequently, compliance to above standards guarantees that module is compatible and works with majority of networking equipment, where is not implemented special algorithm for protection against third party modules. However – we have accumulated expertise in custom-encoded firmware for BIDI-100G-QSFP28-80B in order to make these modules work in almost any brand of equipment.
