Product details
Overview
AFBR-5930Z from Avago Technologies is a 200 MBd SBCON-compliant fiber optic transceiver with 1300 nm InGaAsP LED transmitter and InGaAs PIN photodiode receiver, operating from a single +3.3 V supply and featuring differential PECL-compatible data I/O and single-ended Signal Detect output. It implements IBM ESCON architecture in a 2×5 DIP package with MT-RJ fiber interface for high-reliability channel interconnects.
For engineers reviewing the AFBR-5930Z datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, real-world optical power budgeting guidance, ESD immunity specs (MIL-STD-883C Class 2), SBCON 200 MBd compliance, and board-level decoupling/termination design constraints - all critical for ESCON channel attachment, disk/tape drive interconnects, and point-to-point data links.
Technical Context
The AFBR-5930Z integrates a custom silicon LED driver IC converting differential PECL inputs (ECL-referenced to +3.3 V) into analog LED drive current, and a two-stage receiver comprising an InGaAs PIN photodiode + transimpedance preamplifier IC followed by a quantizer IC for pulse shaping and Signal Detect generation. Both Data Out and Signal Detect outputs are PECL-compatible with ECL reference shifted to +3.3 V.
Receiver outputs RD+ and RD− are differential and squelched when Signal Detect is deasserted; Signal Detect (SD) provides logic "1" at normal optical input levels (>–35.5 dBm avg.) and logic "0" under low-light fault conditions (<–45.0 dBm avg.), with 0.5–4.0 dB hysteresis to prevent chatter. Transmitter Disable (TDIS) is unconnected and reserved for laser-based variants only.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Optical Data Rate | 200 MBd NRZ - supports SBCON-compliant ESCON channel speeds without oversampling or clock recovery circuitry. |
| Transmitter Wavelength | 1280–1380 nm center - optimized for 62.5/125 µm multimode fiber with 147–175 nm FWHM spectral width. |
| Receiver Sensitivity | –35.5 dBm avg. (Signal Detect assert) - defines minimum optical input to maintain valid link status in commercial ESCON systems. |
| Supply Voltage | +3.135 V to +3.465 V - tight 3.3 V tolerance ensures stable PECL logic levels and minimizes supply-induced jitter. |
| ESD Immunity | MIL-STD-883C Method 3015.4 Class 2 (2000–3999 V) - validated protection for handling and board assembly in ESD-controlled environments. |
| Optical Power Budget | ≥12 dB typical - derived from –14.0 dBm min Tx output and –29 dBm min Rx sensitivity, enabling ≥1 km 62.5/125 µm MMF links. |
| Output Rise/Fall Time | 0.35–1.3 ns (data), 0.35–2.2 ns (Signal Detect) - meets SBCON eye-opening requirements at 200 MBd with <1.0 ns systematic jitter. |
Pinout & Package
AFBR-5930Z uses a 2×5 DIP-style package (37.24 mm × 9.8 mm × 49.20 mm max) with MT-RJ fiber receptacle and two solder posts for mechanical anchoring. The housing is molded nonconductive plastic; solder posts connect to chassis ground for EMI integrity and footprint compatibility with SFF transceivers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Receiver Signal Ground (VEE RX) | Direct connection to receiver ground plane - critical for low-noise transimpedance amplifier reference. |
| Pin 2 | Receiver Power Supply (VCC RX) | +3.3 V supply for receiver ICs - requires local 10 µF + 10 nF decoupling per datasheet Figure 4. |
| Pin 3 | Signal Detect (SD) | Single-ended PECL output indicating valid optical input (>–35.5 dBm avg.) - drives upstream LOS-bar inputs directly. |
| Pin 4 | Receiver Data Out Bar (RD−) | Differential PECL complement output - requires external 50 Ω termination to VCC–2 V; no internal termination. |
| Pin 5 | Receiver Data Out (RD+) | Differential PECL true output - paired with RD−; squelched when SD is deasserted. |
| Pin 6 | Transmitter Power Supply (VCC TX) | +3.3 V supply for LED driver IC - separate filtering from RX supply prevents crosstalk-induced jitter. |
| Pin 7 | Transmitter Signal Ground (VEE TX) | Direct connection to transmitter ground plane - isolates high-current LED switching noise from receiver path. |
| Pin 8 | Transmitter Disable (TDIS) | No internal connection - reserved for laser-based products only; left unconnected on AFBR-5930Z. |
| Pin 9 | Transmitter Data In (TD+) | Differential PECL true input - accepts ECL-referenced signals shifted to +3.3 V; no internal termination. |
| Pin 10 | Transmitter Data In Bar (TD−) | Differential PECL complement input - paired with TD+; matched trace routing required for skew control. |
Key Features
| Feature | Design Value |
|---|---|
| SBCON 200 MBd Compliance | Fully compliant with SBCON specification - enables drop-in integration into IBM ESCON-compatible channel subsystems without protocol translation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fiber optic transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HFBR-5930Z | Same 2×5 DIP package, identical pinout, and SBCON 200 MBd compliance; differs in LED aging spec (1.5 dB vs. <1.0 dB) and optical power min/max values. | Valid for ESCON systems where extended optical margin is not required; lacks Avago's enhanced LED lifetime qualification. | Select HFBR-5930Z only if legacy sourcing or cost sensitivity outweighs long-term link stability needs. |
| AFBR-5920Z | Lower data rate (100 MBd), same 1300 nm LED and MT-RJ interface; reduced optical power output (–17.0 dBm typ.) and higher receiver sensitivity (–37.0 dBm). | Suitable for legacy ESCON-100 or non-SBCON 100 MBd links; cannot support full 200 MBd SBCON throughput. | Choose AFBR-5920Z only for backward-compatible 100 MBd deployments where bandwidth headroom is unnecessary. |
Compared with HFBR-5930Z and AFBR-5920Z, the AFBR-5930Z delivers superior optical aging performance (<1.0 dB vs. 1.5 dB) and full 200 MBd SBCON compliance - making it the only option qualified for new ESCON channel attachments requiring long-term link stability and maximum throughput.

FAQ
What is the optical wavelength range supported by the AFBR-5930Z?
The AFBR-5930Z operates with a 1300 nm InGaAsP LED transmitter having a center wavelength range of 1280–1380 nm and a spectral width (FWHM) of 147–175 nm. This range is optimized for 62.5/125 µm multimode fiber and ensures compatibility with ESCON-compliant optical receivers across temperature and aging conditions. The AFBR-5930Z maintains this specification over its full operating temperature range (0°C to +70°C).
Does the AFBR-5930Z support hot-plug operation with MT-RJ fiber cables?
Yes, the AFBR-5930Z is designed for hot-plug operation with MT-RJ fiber cables. Its MT-RJ receptacle is rated for ≥25 kV ESD immunity (Human Body Model), and the internal receiver squelch function disables RD+/RD− outputs when Signal Detect deasserts due to optical loss - preventing invalid data propagation during cable insertion/removal. The AFBR-5930Z also features robust mechanical mounting studs to withstand repeated mating cycles.
What is the recommended termination for AFBR-5930Z differential data lines?
The AFBR-5930Z differential inputs (TD+/TD−) and outputs (RD+/RD−) require external 50 Ω terminations to VCC–2 V (i.e., +1.3 V), as specified in Avago's recommended circuits (Figures 4 and 5). No internal terminations are provided. For optimal signal integrity, use controlled-impedance PCB traces, minimize stub length, and place termination resistors within 5 mm of the AFBR-5930Z pins to suppress reflections and reduce jitter.
How does the Signal Detect function behave on the AFBR-5930Z?
The AFBR-5930Z Signal Detect (Pin 3) outputs PECL logic "1" when received optical power exceeds –35.5 dBm avg. and logic "0" when below –45.0 dBm avg., with 0.5–4.0 dB hysteresis to prevent chatter near threshold. Assert time is ≤500 µs; deassert time is ≤350 µs. This SD output directly drives upstream Loss-of-Signal-bar inputs and triggers receiver squelch, ensuring clean fault signaling in ESCON channel systems.
Is the AFBR-5930Z compatible with standard 2×5 DIP footprints used for other SFF transceivers?
Yes, the AFBR-5930Z complies with the multisource 2×5 DIP footprint definition, including hole pattern, pin spacing, and mechanical envelope. Its solder posts align with standard SFF mounting holes, and its low-profile design fits within the maximum height allowed for MT-RJ connectors. This ensures mechanical and layout compatibility with existing board designs using HFBR-59xx or AFBR-59xx series transceivers.
