Product details

Overview

AFBR-710ASMZ from Broadcom (formerly Avago) is a hot-pluggable SFP+ transceiver for 10Gb Ethernet over multimode fiber, compliant with IEEE 10GBASE-SR/SW standards, featuring an 850 nm VCSEL transmitter and PIN photodiode receiver, 300 m reach on OM3 fiber, extended case temperature range of 0–85 °C, and full digital diagnostic monitoring per SFF-8472.

For engineers reviewing the AFBR-710ASMZ datasheet, pinout, applications, or equivalent options, this page delivers verified electrical interface timing, optical performance limits, real-time DDM parameters (Tx_Bias, Tx_Power, Rx_Power, temperature, Vcc), EMI-compliant mechanical design per SFF-8432, and hot-swap safety features critical for high-density data center switch/router designs.

Technical Context

The AFBR-710ASMZ implements a CML-based 10.3125 GBd serial interface with AC-coupled differential transmit (TD+/TD−) and receive (RD+/RD−) paths, integrated laser driver and post-amplifier ICs, and dual-wire serial management via SCL/SDA at up to 400 kHz. Its optical subassembly uses Avago's proprietary 850 nm VCSEL and PIN detector optimized for OM3/OM4 MMF.

Digital diagnostics are implemented across two EEPROM pages: address 0xA0 (SFF-8431 compliance) and 0xA2 (SFF-8472 DDM), enabling real-time monitoring of Tx_Bias, Tx_Power, Rx_Power, module temperature, and supply voltage - all used for Predictive Failure Identification, Compliance Prediction, and Fault Isolation without host SERDES involvement.

Key Specifications

Parameter	Value and Actual Design Meaning
Data Rate	10.3125 GBd - matches IEEE 10GBASE-SR line rate; enables interoperability with standard 10GbE PHYs
Optical Wavelength	840–860 nm - centered on 850 nm VCSEL peak for optimal MMF coupling and modal dispersion margin
Link Reach	300 m on OM3 MMF - meets IEEE 10GBASE-SR spec; requires no mode conditioning or special cabling
Operating Temp	0–85 °C case temperature - supports deployment in high-heat-density switches and top-of-rack systems
Power Dissipation	600 mW typical - enables thermal management in ≥48-port SFP+ line cards without forced airflow
Diagnostic Interface	SFF-8472 compliant two-wire (SCL/SDA) - provides host-accessible real-time Tx/Rx metrics and fault flags
EMI Performance	Meets FCC Class B, CISPR 22 Class B - metal housing and shielded design reduce system-level filtering requirements
Laser Safety	IEC 60825-1 Class 1 - built-in eye safety circuit disables transmitter if output exceeds single-fault-tolerant limit

Pinout & Package

AFBR-710ASMZ uses the standardized 20-pin SFP+ edge connector per SFF-8431 and SFF-8432, housed in a metal-shielded, RoHS-compliant pluggable module with LC duplex optical interface. The package supports hot insertion and complies with INF-8074 mechanical specifications.

Pin/Terminal	Circuit Role	Design Meaning
VeeT (Pins 1, 17, 20)	Transmitter signal ground	Provides low-inductance return path for TD+/TD−; isolated from chassis ground to suppress common-mode noise
TX_FAULT (Pin 2)	Open-collector fault indicator	Asserts high on catastrophic laser failure; latched until TX_DISABLE toggle or power cycle
TX_DISABLE (Pin 3)	LVTTL input control	High or open disables VCSEL; internal 4.7–10 kΩ pull-up ensures safe default-off state
SDA / SCL (Pins 4–5)	Two-wire serial data/clock	Accesses SFF-8472 DDM registers (0xA2) and SFF-8431 ID memory (0xA0); requires external pull-ups
RX_LOS (Pin 8)	LVTTL loss-of-signal flag	High indicates absence of valid modulated optical input; mirrored in DDM byte 110, bit 1
TD+/TD− (Pins 18–19)	CML transmit input	Differential CML interface accepts 10.3125 GBd signals; internally AC-coupled and 100 Ω terminated
RD+/RD− (Pins 12–13)	CML receive output	Differential CML output drives host SERDES; requires external 100 Ω termination at receiver end
VccT / VccR (Pins 16, 15)	+3.3 V supply rails	Separate transmitter/receiver supplies; must not differ by >0.5 V to prevent damage

Key Features

Feature	Design Value
Predictive Failure Identification	Monitors real-time Tx_Bias and Tx_Power trends to detect early laser degradation before link errors occur
Compliance Prediction	Enables host to verify operating voltage, temperature, and Rx_Power against IEEE 10GBASE-SR limits pre-failure
Fault Isolation	Combines Tx_FAULT, RX_LOS, and DDM metrics to distinguish local transmitter, remote transmitter, or fiber plant faults
Hot-Pluggable EMI-Optimized Housing	SFF-8432 metal cage design achieves Class B EMI margins even in 48-port 1U switch configurations
Class 1 Laser Safety	Hardware-enforced shutdown on over-power events; certified to IEC 60825-1 and US FDA CDRH AEL Class 1
Integrated AC Coupling & Biasing	Eliminates need for external DC-blocking caps or termination resistors on host board per SFF-8431

Equivalent & Alternatives

The following parts are listed as comparable options for similar 10GBASE-SR SFP+ transceiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AFBR-710SMZ	Same optical specs but rated for 0–70 °C case temperature; lacks extended-temp qualification	Preferred for controlled-environment enterprise gear where ambient cooling is guaranteed	Select AFBR-710SMZ only when thermal headroom permits lower max case temp; AFBR-710ASMZ required for uncontrolled or high-power-density chassis
AFCT-739SMZ	10GBASE-LR variant: 1310 nm DFB laser, 10 km SMF reach, higher power consumption (~1 W), different wavelength and dispersion tolerance	Used for campus backbone or metro links requiring single-mode fiber distance extension	Not interchangeable - AFCT-739SMZ requires SMF infrastructure and cannot operate on MMF; choose only for long-haul or hybrid fiber plant needs

Compared with AFBR-710SMZ, the AFBR-710ASMZ adds 15 °C higher upper-case-temperature margin for thermal resilience in compact switches; compared with AFCT-739SMZ, it trades 10 km SMF reach for lower cost, lower power, and native OM3 compatibility - making it the sole fit for standardized short-reach data center MMF deployments.

The AFBR-710ASMZ belongs to Avago's legacy SFP+ transceiver product line, engineered specifically for high-port-density 10GbE equipment targeting IEEE 10GBASE-SR/SW compliance, thermal robustness, and embedded digital diagnostics in carrier-grade and cloud-scale systems.

FAQ

What is the maximum supported link distance for AFBR-710ASMZ on OM4 fiber?

The AFBR-710ASMZ supports up to 400 meters on 50 µm OM4 multimode fiber, as specified in its IEEE 10GBASE-SR compliance documentation and confirmed in Table 4 of the official datasheet. This exceeds the 300 m OM3 limit and aligns with TIA-492AAAC launch condition requirements for 10GbE MMF operation.

Does AFBR-710ASMZ require external AC coupling capacitors on the host board?

No, the AFBR-710ASMZ integrates AC coupling capacitors and termination resistors per SFF-8431 specification, eliminating the need for external components on the TD+/TD− and RD+/RD− signal paths. Host board design must only provide proper CML impedance control and power filtering as shown in Figure 3 of the datasheet.

How does the digital diagnostic monitoring (DDM) in AFBR-710ASMZ support predictive maintenance?

The AFBR-710ASMZ implements SFF-8472 DDM to expose real-time values for Tx_Bias current, Tx_Optical_Power, Rx_Optical_Power, module temperature, and supply voltage. By trending these parameters - especially rising Tx_Bias with stable Tx_Power - system firmware can predict laser end-of-life before BER degradation occurs, enabling proactive replacement.

Is AFBR-710ASMZ compatible with SFP cages designed for older SFP modules?

Yes, the AFBR-710ASMZ complies with SFF-8432 Improved Pluggable Formfactor (IPF) and is mechanically compatible with INF-8074 and SFF-8431/2 compliant SFP cages. However, electrical interoperability requires host board support for SFP+ signaling levels and control logic - legacy SFP-only hosts will not recognize or power the AFBR-710ASMZ.

What safety certifications apply to AFBR-710ASMZ?

The AFBR-710ASMZ is certified Class 1 Laser Product per IEC 60825-1 and US FDA 21 CFR Part 1040.10/1040.11 (CDRH), with certification numbers CDRH 9720151-128 and TÜV file R 72121699. It also meets RoHS Directive 2002/95/EC and UL Component Recognition E173874 for IT equipment safety.
