Product details
Overview
AFBR-89CEHZ from Broadcom is a four-channel, pluggable QSFP28 multimode fiber optic transceiver for 100 Gigabit Ethernet applications. It delivers 103.125 Gb/s aggregate bandwidth (4×25.78125 Gb/s), supports 300 m reach over OM4 MMF via MPO connector, operates at 850 nm, and conforms to IEEE 802.3bm Clause 95 (100GBASE-SR4) and CAUI-4 with RS-FEC.
For engineers reviewing the AFBR-89CEHZ datasheet, pinout, applications, or equivalent options, this module serves as a hot-pluggable, Class 1 eye-safe optical interconnect solution requiring precise compliance with SFF-8636 Rev 2.9, digital diagnostics (TWS interface), and thermal management within 0°C to +70°C case temperature.
Technical Context
The AFBR-89CEHZ integrates a 4-channel VCSEL transmitter array and 4-channel PIN photodiode receiver array, each with integrated CDR, equalization, and retiming-configurable for bypass in alternative data rate modes. Its electrical interface uses a 38-pin QSFP28 edge connector with AC-coupled CML I/O and internal 100 Ω termination on TX side.
Digital diagnostics are implemented via a two-wire serial (TWS) interface supporting real-time monitoring of per-channel laser bias current, TX output power, RX input power, module temperature, and supply voltage-with alarm/warning thresholds, latched flags, and hardware interrupt signaling (IntL) for loss-of-signal and parameter violations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 100GbE SR4 transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AFBR-89CDZ | Same QSFP28 form factor and 100GBASE-SR4 compliance, but rated for 100 m over OM3 (not OM4); lower max TX power (–7.0 dBm min vs –8.3 dBm) | Limited to shorter-reach OM3 deployments; not suitable for 300 m OM4 links | Select AFBR-89CDZ only when cost sensitivity outweighs reach requirement and OM3 infrastructure is fixed. |
| AFBR-89CEZ | Identical electrical/optical specs and pinout, but lacks shielded housing and EMI-optimized metal enclosure per AFBR-89CEHZ datasheet Section 1 | Higher radiated emissions risk in dense chassis; unsuitable for FCC/EN55022 Class B systems without additional shielding | Choose AFBR-89CEZ only in controlled lab or non-certified equipment where EMI margin is verified externally. |

FAQ
What is the maximum supported fiber distance for AFBR-89CEHZ?
The AFBR-89CEHZ supports up to 300 meters over OM4 multimode fiber and 170 meters over OM3 fiber, as defined in IEEE 802.3bm Clause 95. This 300 m OM4 reach is enabled by its eSR4 implementation with mandatory RS-FEC correction and optimized 850 nm VCSEL performance. The AFBR-89CEHZ datasheet explicitly states this distance under Recommended Operating Conditions on page 6.
Does AFBR-89CEHZ support retimer bypass functionality?
Yes, the AFBR-89CEHZ supports per-channel retimer bypass via its two-wire serial (TWS) interface, allowing the transmitter and receiver CDR/EQ blocks to be disabled. This enables alternative data rate transmission modes beyond the default 4×25.78125 Gb/s configuration. The capability is documented in the Transmitter and Receiver sections of the AFBR-89CEHZ datasheet (pages 3–4).
What diagnostic parameters are monitored by AFBR-89CEHZ?
The AFBR-89CEHZ monitors per-channel transmitter laser bias current, transmitter optical output power, receiver optical input power, plus module case temperature and +3.3 V supply voltage-all accessible via the TWS interface. Each parameter has configurable alarm/warning thresholds and latched interrupt flags. These diagnostics are fully specified in the Digital Diagnostic Monitoring section (page 4) and memory map (page 5) of the AFBR-89CEHZ datasheet.
Is AFBR-89CEHZ compliant with QSFP28 MSA and IEEE standards?
Yes, the AFBR-89CEHZ complies with QSFP28 MSA SFF-8636 Rev 2.9, SFF-8661 mechanical specification, and IEEE 802.3bm Clauses 83E (CAUI-4) and 95 (100GBASE-SR4). It also meets Class 1 laser safety per IEC 60825-1 and FCC/EN55022 EMI requirements due to its shielded metal housing. Compliance statements appear in the Features, Regulatory Compliance Table, and Application Reference Diagram sections of the AFBR-89CEHZ datasheet.
What is the operating temperature range for AFBR-89CEHZ?
The AFBR-89CEHZ operates across a case temperature range of 0°C to +70°C, measured at the location shown in Figure 8 of the datasheet. This range is validated under Recommended Operating Conditions (page 6) and applies to continuous operation; prolonged exposure at the +70°C limit may impact reliability and is discouraged per footnote "a" in the datasheet.
