Comcast Corp. (Nasdaq: CMCSA, CMCSK) is setting its sights on some small Converged Cable Access Platform (CCAP) deployments before the end of 2012, Vice President of Access Architecture Jorge Salinger said Monday during a Light Reading Cable webinar on the topic. “We hope to deploy,...
Fiber constraints on FTTH deployments ease
Several sources from the vendor community asserted yesterday at the FTTH Conference in Dallas, TX, that fiber shortages that had hindered the completion of broadband stimulus fiber-to-the-home (FTTH) network deployments have lessened. Delivery schedules are returning to normal, particularly for the larger carriers, the sources...

CABLE S-PARAMETERS THROUGH MEASUREMENT
Cable S-Parameters through Measurement setup is shown in Figure 4. The through measurement setup shown is for cable end B to cable end A with the response measured B’ to C’. The procedure is then repeated to measure cable through response from end A to...
CABLE S-PARAMETERS CROSSTALK MEASUREMENT
Cable S-parameters crosstalk measurements setup is shown in Figure 5. The crosstalk measurement setup shown is for the cable end B measured from B’ to C’. The procedure is then repeated to measure cable crosstalk for the other end. OC3/STM-1 SFP transceiver
S-PARAMETERS TEST METHOD PROCEDURE
In order to calculate the cable parameters as defined in SFF-8431 table 37, following test procedure is required: •Measure S-parameters for MCB-HCB from point B” to B, see 3.1.1 •Measure the s4p for through S-parameters for cable end 1 to cable end 2, see 3.1.2...
SFP+ ACTIVE CABLES TYPE I (FOR OPERATION WITH A LIMITING HOST)
SFP+ Active Cable’s Type I are assemblies that operate with the SFP+ limiting hosts defined in Chapter 3 of SFF-8431. Specifically, the active cable input must satisfy the SFP+ module transmitter input specifications at B’ in Table 16 of SFF-8431 and tolerance specifications at B”...
